Hidden Valley is 1,000 acres of protected land in Jefferson, rich with a variety of habitat and terrain including over a mile of shore front on Little Dyer Pond. Miles of multi-use trails great for hiking and biking, rolled and groomed XC ski trails, and several rustic huts and tent sites are waiting for you. HVNC is your forest. Come learn about sustainable forestry or attend a full moon paddle.  Join us at one of more than 30 programs to learn new skills or just explore this gem of a wilderness for yourself! All are welcome; $5 day-use donations from non-members are accepted at the gatehouse. HVNC is located at 131 Egypt Road in Jefferson.

Three-season Self-guided Trail Running

Pick one of two marked 3-mile loops so you can compare training runs! One course is moderate terrain, the other includes some hills to get your heart pumping. Start at the Barn for both; fill your water bottle at the pump there. Need a goal? Set your sights on our Race Through the Woods on September 25th!

Natural Ingredients for Curious Students

Fourth-grade students from area schools are brought out to HVNC each month to engage in conservation education tied to Maine’s state standards for science curriculum.  Students participate in dynamic science lessons, leading their own investigations and experiments, collecting information and exploring – all led by an award-winning outdoor educator. One teacher shared that at HVNC “every child is a scientist, seeing the world through the lens of observation and curiosity,” and that participating in this program was “one of the best decisions I have made in my teaching tenure.” Funded by both grants and private contributions, this program helps build confidence, promotes creativity, gets kids moving and makes kids think.
